DEVICE FOR RECOVERING SUNliCEN LOGS.

Clear old and State of Pennsylvania, lave invented certain new anduseful Improve- .ments in Devices for Recovering Sunken and I do herebydeclare the following a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappcrteins to make and use the same.

For recovering logs from the bottoms of rivers, streams or dams, I haveproduced a. device having the form of e pick and the function of" a dogwhich is driven into he log is then drawn ashore by the driven dog, andin the claims a n led hereto I will point out the parts and IL. hinationof parts which constitute. my inven tion, in connection with theaccompanying drawings, in Which,-

Figure 1 shows a log on the bottom o? a river and my recovering clogdevice driven into it. Fig. 2 is an enlarged view of the driven dogdevice from which the drive-rod has been removed. Fig. 3 is a like viewof the dog device and its drive-rod, the (ominotion being in section toShow the means fi'or detaching the drive rod from the dog. Fig. 4 is adetail sectional view of the atteching end of the rlrivc-rod showing itsspring catch and socket. Fig. 5 is a horizontal section taken at thebase of the stud lookin upward and showing the spring catch of the driverod for locking engagement with the stud. Fig. 6 is a like view showingthe drive rod in the position in which it is rotated to disengage it bylifting it from the stud oi" the rodv when the log is to he drawnashore.

The log engaging part has the function of a dog and, the form of a )lCk,the point 1 ol which is driven into the leg, while it {Milling line isconnected to the end of t e dog; shan 3, the position of which iseuhsiiin tially parallel with the log when dogged thereto, so that thepull upon the log will he in the direction of its length.

A stud 4, rojects from handle about in a. vertical line with the pick.

A notch 10 may he made at the underside of the shank toreceive a crow-bar when it is desired to draw the pick-point from thelog.

I claim:

1. In a device for recovering sunken logs, a shank having a polling lineat one end, a pick-point at its other end substantially at right anglesto the shank, a stud on the shank shove the pick-point, a drive-rodhaving no fixed connection with the device,

and means on the drive-rod and on the stud adapted for engagement anddisengagement by the rotation of the rod upon the stud to automaticallyengage and disengage the rod from the stud.

2. In a device for recovering sunken logs, a shank having at one end apick-point and a stud on the shank above the pick point having ashouldered recess or notch at its base, the other end of the shank havina pulling line, and a drive-rod having a sec et end, a spring catchsecured to the socket end and adapted to be automatically engaged withand disen aged from the shouldered recess of the stu 3. In a device forrecovering sunken logs, a shank having at one end a p|ck-point, and astud on the shank above the pick-point, the other end of the shankhaving a pulling line, and a drive-rod having a socket end, and meansfastened to said rod and entering said socket adapted to engage the studand to release said engagement by a rotation of the drive-rod on thestud.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
